Abstract: An emotion estimating system includes a learning model and an estimation unit. The learning model accepts external information and biological information as input, and outputs an emotion of a user. The estimation unit changes a weighting applied to external information about the user detected by a first detector and a weighting applied to biological information about the user detected by a second detector in accordance with a situation around the user, and estimates the emotion output as a result of inputting external information and biological information changed by the respective weightings into the learning model as the emotion of the user.

Abstract: A dialogue apparatus includes a memory, an estimation unit, and a dialogue unit. The memory associatively stores a certain topic and a change in an affective state of each user before and after a dialogue on that topic. The estimation unit estimates an affective state of a user using information obtained from a detector that detects a sign that expresses the affective state of the user. The dialogue unit extracts, from the memory, a topic where the affective state obtained by the estimation unit matches or is similar to a pre-dialogue affective state and where a target affective state matches or is similar to a post-dialogue affective state, and has a dialogue on the extracted topic with the user.
